Class R1R1Function

java.lang.Object
  org.jcurl.math.R1RNFunctionImpl
      org.jcurl.math.R1R1Function

All Implemented Interfaces:

Serializable, R1RNFunction

Direct Known Subclasses:

CSplineInterpolator, Distance2DSq, Polynome

public abstract class R1R1Function
extends R1RNFunctionImpl

A one-dimensional function f : R^1 -> R^1. Because this is the same as a 1-dimensional curve it extends R1RNFunctionImpl.
